I added a multiple-day calendar event in the August calendar in iCal on my 10.5.4 Mac this morning. I checked MobileMe calendar a minute or so later and nothing. Okay, so I got tired of waiting and got on with my life. Just checked in a few minutes ago (3+ hours later) and still nothing. Everything else is there, which was entered prior to the big MobileMe change-over. Oh well, I guess there's still some teething pains. Hope the fix this kind of issues within the next 89 days, otherwise I'll have to give serious thought to whether or not to renew.
